3D Accel & Dual Monitor?
 

Hi everyone!

I just installed Fedora Core 1 and am very pleased so far, I have setup ATI drivers alot easier then I thought as well as Dual Monitors worked perfectly!

I know I have 3D Accel working because when I do fglxinfo it says "Radeon 9800" etc etc...

But when I try to run Tux Racer or any 3D game it crashes XFree, basically I just want to know if you can get 3D working with dual monitors?

Sorry if this is a double post but I searched and couldnt find anything on the subject

Thanks :)

X guys check me on this: but I thought DRI was incompatable with the xinerama extension? or are you not using xinerama for dual monitors?

I take that back. After a check over at dri.sourceforge.net it seems there is some (limited) support for xinerama and multihead displays. What ATI drivers are you using and what's the cards?

Hi,

Im using the latest fgrlx drivers from ATI's website (latest as in last week), I did not enable xinerama for setting up the dual monitors. I used the fglrxconfig to have it make my XF86Config using dual monitors.

If I wasnt at work I would post the config here right now...

BTW glgears works, I get 3500-3800 fps when I run it in console mode but nothing else works in X.

Specs are in sig, but using a Radeon 9800 Non pro.

I'm using a 9700 pro, not sure about fglrx's support for dual heads so I'll see what I can figure out when I get home on Saturday

3-D on two monitors hauls two-handed heiney!

k0rupt, you're right about ATI's support for dual monitoring and you said that glxgears report acceptable framerates. I don't have dual monitors so I'm afraid I can't actually test anything out, but if you'd like to post the error messages from tuxracer and other games I'll do my best to help out.

I haven't been able to notice a actual error msg, what is the cmd to exit to cmd line? init 3?

When I run Tux Racer it crashes the X server completely and brings me back into login screen for X...

very wierd, thanks for the help guys... once I get this working I think I am going to ditch Microsoft for good!

if you can turn off the graphical login for now it would be a great help. Then when X crashes you can examine its log file to determine what went wrong. Also you could try running tuxracer from the command line dumping all output to a text file.

tuxracer 2>&1 1>output.txt

this should dump all messages both stderr and stdout to output.txt

which file to edit to turn off graphical login?

i remember it has something to do with editing a file so its like "0:3:0" insted of "0:5:0"

sorry for being a :newbie: :)

uhm; well there might be a better way (GUI) but the way to do it by hand is to edit /etc/inittab and instead of letting the system go to runlevel 5 have it stop at runlevel 3.

this is done with the line:
id:3:initdefault:

thanks, sorry for asking when I could have searched but I am at work and I could not doing right away if I wanted to...

I will go ahead and post some errors when I get home @ 8pm EST tonight.

thanks again!

okay, I got the error msg... says it cant find a video device... heres the actual error msg:

" *** Tux Racer error: Couldn't initilize SDL: No available video device. "

I don't think this'll help much but I would very much like to get 3D accel working.... althought OpenGL screensavers work I don't know why Tux Racer & Chromium don't work.

Your SDL libraries could be having an issue with the setup, or perhaps the libraries simply don't know which screen to use... take a look at SDL to determine if it has any issues with dual monitor machines.

perhaps running tuxracer in windowed mode _might_ help, 50-50 shot.

here's a post that might be informative:

i hope that will be my only problem related to 3D Accel, i'm going to try enemey territory later to see if this problem has affected other 3D graphics as well...

how would one run tuxracer in windowed mode?

thanks alot
